FERDINAND E. CANDA, OF NE\V YORK, N. Y.

DUMPlNG-CAR.

SPECIFICATION forming part of Letters Patent No. 396,140, dated January 15, 1889.

Application filed March 9, 1888- Serial No- 266,674. (No model.)

To all whom it may concern.-

Be it known that I, FERDINAND E. CANDA, of the city, county, and State of New York, have invented a new and Improved Dumping-Car, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a partial side elevation of a dumping-car to which my improvement has been applied. Fig. 2 is an enlarged vertical transverse section of the same, the section being taken on line x :0 in Fig. 1. Fig. 3 is a plan view of a portion of the car-bottom with the floor removed. Fig et is a longitudinal section taken on line y y in Fig. 3, and Fig. 5 is an enlarged transverse section taken 011 line 2 z in Fig. 3.

Similar letters of reference indicate corresponding parts in all the views.

This invention relates to clumping-cars the floors of which are provided with one or more dischargeapertures that are closed, when required, by a sliding door or doors, as distinguished from a hinged door or doors, which are objectionable. Such dumpingcars are superior in many respects to those in which the entire floor has been arranged for inclination at a suitable angle for dumping, as also those in which the car has been provided with a hopper-shaped bottom having doors atthe point of discharge.

My invention consists in certain novel constructions and combina1 ions of parts in a dumping-car of the description above referred to, substantially as hereinafter described, and pointed out in the claims, and whereby not only great strength and perfect efficiency are secured,- but the sills which support the floor of the car are kept intact, and also virtually serve to carry or support the sliding door or doors that control the dumping aperture or apertures in the floor of the car.

In carrying out my invention I may apply any required number of the sliding doors to the car, and may arrange them in any desired position in the door of the car. In the present case I have shown two such doors in the bottom of the car, and as the said doors and fittings are precisely alike a description of one of them will answer for both.

The platform of the car is of the usual construetion, consisting of the floor A, laid upon the longitudinal sills B O, the said longitudinal sills being in turn supported by the crosssills D, and the entire structure of the carplatform being stiffened by longitudinal truss-rods o, in the usual way. The side sills, B, are provided with stake-pockets b for receiving stakes c, which support the side boards, e. Above the space between two of the longitudinal sills, preferably the exterior sill, B, and the adjacent intermediate sill, C,

in the fioor A, is formed a discharge-opening, E, whose width is a little less than that of the space between the said sills, and Whose length is as great as may be desired. To adjacent sides of the said sills B C are secured hooks or brackets f, preferably formed of bars of iron or steel bent twice at right angles, the arms thus made being parallel with each other, the longer arm of each hook or bracket being secured to the sills by bolts g g. lVithin the shorter arms of the hooks or brackets, and resting upon the horizontal part thereof, is a'bar or rail, h, which extends parallel with the inner face of the sills B C and with the floor A. The bars or rails 72. are held in place in the hooks or brackets f by distance-pieces 1' and by the bolts g, which pass through both arms of the hook or bracket, through the bar or rail 71, and through the said distance-pieces. The bars or rails h are prolonged beyond one end of the opening E in the car-platform to support the sliding door G when open.

The sliding door G is formed of planks j, either with or without an iron covering-plate, 1;. To the under surface of the door are fitted the metallic cleats Z, having the angled ends m, which extend a short distance downward over the outer surfaces of the bars or rails h, thus forming a complete guide for the sliding door G. The edges of the door G are beveled from the upper surface, and above the opposite edges of the door and surrounding same are arranged beveled cleats a, which are secured to the sills l3 0 and extend over the edges of the door beyond the beveled parts thereof. The door may be moved horizontally in both directions upon or along the bars or rails by any suitable operating mechanism such. as Windlass and chain, endless screw, or

rack and pinion, or other well-known. devicesand therefore I do not limit myself to any particular form of operating mechanism; but. for the purpose of illustration I will now describe a windlass and chain used by me and shown in my said drawings for said purpose.

Near one end of the opening E, and near the mid-length. of the bars or rails 74, a windlass, F, is journaled in boxes secured to the sills B C. To the windlass are attached two chains, 0 0, arranged to be wound in opposite directions upon the windlass If, so that as one chain is wound upon the windlass the other will be unwound. The chain 0 is attz'tchedby an eye, 1), to the end of the door G, which is to be drawn when the said door is closed, and the chain 0' is attached by an eye, 1), to the opposite end of the door. The axle oi the windlass is prolonged beyond the side of the car and furnished with a ratchet-wheel, II, secured thereto, and an angled. lever, I, mounted loosely upon the said axle. To the shorter arm of the lever I is pivoted a double pawl, .I, which is adapted to engage the ratchet-wheel ll, so as to move it in either direction, according as the door G is to be opened or closed. When the pawl and ratchet: is arranged so as to wind the chain 0 and allow the chain 0 to unwind as the lever I is oscillated, the door (1 will be moved along the bars or rails 71 as far as is necessary for the dumping of the load. When the pawl and ratchet is arranged to wind the chain 0 and unwind the chain 0, the door G will be closed when the lever I. is oscillated.

\Vith my improved construction the clogging ot' the door prevented by allowing the dust and smaller particles oi material. to escape between the beveled cleats n. and beveled edges of the door G and fall between thebars or rails 7i and the sills l This provides a free or open space bet ween the edges of each door and its supports tor the escape of small particles which could otherwise clog the door.

It will be observed that the portion of the load lying upon the door G is supported by the bars or rails 11, each securely held in position by the suppm-ting books or brackets f, and that the said door is capable of sustaining as much weight as any portion of the carlioor of like area. For this reason the car is able to carry a greater load than a car provided with hinged doors for dumping.

Another advantage secured by my improvement is, that the application of the sliding doors does not n( eessitate the cutting of the sills or any change in the arrangement of the longitudinal truss-rods. The car may, therefore, have the full strength of aplatform-car ot' the best construction.

llavin g thus described my invention, I elai m as new an d desire to secure by Letters Iaten t- 1.
